SAVINGS RESTORATION PLAN

FOR NISOURCE INC. AND AFFILIATES

As Amended and Restated Effective May 13, 2011

ARTICLE I

BACKGROUND AND PURPOSE

1.1 Background. Prior to January 1, 2004, Columbia Energy Group sponsored the Savings Restoration Plan for Columbia Energy Group for eligible executives of Columbia Energy Group and certain Affiliates. Effective January 1, 2004, NiSource Inc., the parent company of Columbia Energy Group, assumed sponsorship of the Savings Restoration Plan for Columbia Energy Group, renamed the Plan the Savings Restoration Plan for NiSource Inc. and Affiliates, and broadened the Plan to include all employees of NiSource Inc. and Affiliates.

The Plan was amended and restated effective January 1, 2004, and amended effective January 1, 2005. The Plan was then amended and restated again effective January 1, 2005, to comply with Code Section 409A, and guidance and regulations thereunder, with respect to benefits earned under the Plan from and after January 1, 2005. Benefits under the Plan earned and vested prior to January 1, 2005 shall be administered without giving effect to Code Section 409A, and guidance and regulations thereunder. The provisions of the Plan as set forth herein apply only to Participants who actively participate in the Plan on or after January 1, 2005. Any Participant who retired or otherwise terminated employment with the Company and all Affiliates prior to January 1, 2005 shall have his or her rights determined under the provision of the Plan as it existed when his or her employment relationship terminated.

The Plan was further amended and restated, effective January 1, 2008, to provide for mandatory lump sum payments of small account balances in accordance with Code Section 409A. The Plan was amended and restated again, effective January 1, 2010, to contain provisions that eliminate mid-year enrollment into the Plan and to allow Participants who make Roth Contributions to a Basic Plan to participate in this Plan. The plan was further amended and restated, effective January 1, 2010, to restore certain Employer Contributions given to Participants who are classified as “exempt employees” by the Employer and who are hired or rehired on or after January 1, 2010.

The Plan is amended and restated again, effective May 13, 2011 or as otherwise stated herein, to restore Profit Sharing Contributions that otherwise would have been contributed to Participants under the Basic Plan (if not subject to the Limits, defined below) and to transfer all administrative authority with respect to the Plan (including the authority to render decisions on claims and appeals and make administrative or ministerial amendments) from the ONC Committee to the Benefits Committee.

1.2 Purpose. The purpose of the Plan is to provide for the payment of savings restoration benefits to employees of NiSource Inc. and Affiliates, whose benefits under the Basic Plan are subject to the Limits or affected by deferrals into the DCP, so that the total savings plan benefits of such employees shall be determined on the same basis as is applicable to all other employees of the Company. The Plan is adopted solely (1) for the purpose of providing benefits to Participants in the Plan and their Beneficiaries in excess of the Limits imposed on qualified plans by Code Section 401(a)(17) and any other Code Sections, by restoring benefits to such Plan Participants and Beneficiaries that are no longer available under the Basic Plan as a result of the Limits, and (2) for the purpose of restoring benefits to Plan Participants and Beneficiaries that are no longer available under the Basic Plan as a result of the Participant’s deferrals into the DCP.

4

allocations in the Basic Plan, shall be eligible to become a Participant in the Plan as of January 1 of such Plan Year. Any Participant in the Plan on December 31, 2004 shall continue as a Participant after that date. If an Employee who was not expected to be eligible to become a Participant in a given Plan Year subsequently qualifies because his or her Compensation exceeds the Limits for that Plan Year, or because he or she becomes eligible for, or begins to participate in, the DCP, such Employee shall be eligible to participate in the Plan as soon as practicable after this determination has been made or deferrals begin.

3.3 Method of Becoming a Participant.

AND PAYMENT OF BENEFITS

6.1 Termination of Participation. A Participant’s participation in the Plan shall terminate at separation from service with the Company and all Affiliates for any reason, including Disability or death.

Upon his or her separation from service, a Participant, his or her spouse, or his or her Beneficiary or legal representative shall be entitled to 100% of the Participant’s Supplemental Savings Account credited with Interest, if applicable, through the calendar month preceding the date payment is made to the Participant (or to his or her spouse, legal representative or Beneficiary in the case of his or her incapacity or death).

(i) The Pre-2005 Benefit payable under the Plan to a Participant or his or her spouse, Beneficiary, or legal representative shall be paid in the same form under which the Basic Plan benefit is payable to the Participant or his or her spouse, Beneficiary, or legal representative. The Participant’s election under the Basic Plan of any optional form of payment of his or her Basic Plan benefit (with the valid consent of his or her surviving spouse where required under the Basic Plan) shall also be applicable to the payment of his or her Pre-2005 Benefit under the Plan.

(ii) Payment of the Pre-2005 Benefit under the Plan to a Participant or his or her spouse, Beneficiary, or legal representative under the Plan shall commence on the same date as payment of the benefit to the Participant or his or her spouse, Beneficiary, or legal representative under the Basic Plan commences. Any election under the Basic Plan made by the Participant with respect to the commencement of payment of his or her benefit under the Basic Plan shall also be applicable with respect to the commencement of payment of his or her Pre-2005 Benefit under the Plan.

(iii) Notwithstanding the provisions of paragraphs (i) and (ii) above, an election made by the Participant under the Basic Plan with respect to the form of payment of his or her Pre-2005 Benefit thereunder (with the valid consent of his or her surviving spouse where required under the Basic Plan), or the date for commencement of payment thereof, shall not be effective with respect to the form of payment or date for commencement of payment of his or her Pre-2005 Benefit under the Plan unless such election is expressly approved in writing by the Plan

10

Administrator. If the Plan Administrator shall not approve such election in writing, then the form of payment or date for commencement of payment of the Participant’s Pre-2005 Benefit under the Plan shall be selected by the Plan Administrator at its sole discretion.

(i) Payment of a Post-2004 Benefit in accordance with this Section 6.3 shall commence within 45 days after the Participant’s date of separation from service with the Company and all Affiliates, or, if later, within such timeframe permitted under Code Section 409A, and guidance and regulations thereunder.

(ii) The Post-2004 Benefit shall be payable in a form elected by a Participant no later than December 31, 2005. Notwithstanding the preceding sentence, in the case of an Employee who becomes a Participant on or after January 1, 2005, the aforementioned election with respect to the form of payment of a Post-2004 Benefit shall be made within 30 days after the date the Participant first becomes eligible to participate, and such election shall be effective with respect to Compensation related to services to be performed subsequent to the election; provided that such a Participant shall not be considered first eligible if on the date he becomes a Participant he participates in any other nonqualified account balance plan that is subject to Code Section 409A, maintained by the Company or an Affiliate. The form of payment shall be elected by the Participant at the time he makes the election described in the first or second sentence of this paragraph (iii) from among those forms of payment available at that time under the Basic Plan. If a timely payment election is not made by a Participant, payment shall be made in a lump sum.

(iii) A Participant cannot change the time or form of payment of a Post-2004 Benefit under this Section 6.3(b) unless (A) such election does not take effect until at least 12 months after the date the election is made, (B) in the case of an election related to a payment not related to the Participant’s Disability or death, the first payment with respect to which such new election is effective is deferred for a period of not less than five years from the date such payment would otherwise have been made, and (C) any election related to a payment based upon a specific time or pursuant to a fixed schedule may not be made less than 12 months prior to the date of the first scheduled payment.

(iv) Notwithstanding any preceding provision of this Section 6.3(b), a Participant may change an election with respect to the time and form of payment of a Post-2004 Benefit, without regard to the restrictions imposed under paragraph (iii) next above, on or before December 31, 2006; provided that such election (A) applies only to amounts that would not otherwise be payable in calendar year 2006, and (B) shall not cause an amount to be paid in calendar year 2006 that would not otherwise be payable in such year.

11

(v) Notwithstanding any other provision of the Plan, in no event can a payment of a Post-2004 Benefit to a Participant who is a Specified Employee of the Company or an Affiliate, at a time during which the Company’s capital stock or capital stock of an Affiliate is publicly traded on an established securities market, in the calendar year of his or her separation from service be made before the date that is six months after the date of the Participant’s separation from service with the Company and all Affiliates, unless such separation is due to death or Disability.

A Participant shall be deemed to be a Specified Employee for purposes of this subparagraph (v) if he or she is in job category C2 or above with respect to the Company or the Affiliate that employs him or her; provided that if at any time the total number of Employees in job category C2 and above is less than 50, a Specified Employee shall include any person who meets the definition of a Key Employee set forth in Code Section 416(i) without reference to paragraph (5). A Participant shall be deemed to be a Specified Employee with respect to a calendar year if he is a Specified Employee on September 30th of the preceding calendar year. If a Specified Employee will receive payments hereunder in the form of installments or an annuity, the first payment made as of the date six months after the date of the Participant’s separation from service with the Company and all Affiliates shall be a lump sum, paid as soon as practicable after the end of such six-month period, that includes all payments that would otherwise have been made during such six-month period. From and after the end of such six month period, any such installment or annuity payments shall be made pursuant to the terms of the applicable installment or annuity form of payment.

Notwithstanding any other provision in this Section 6.3, if (1) the sum of the Participant’s Pre-2005 Benefit and Post-2004 Benefit does not exceed the applicable dollar limit under code Section 402(g)(l)(B) and (2) this sum is the entirety of the Participant’s interest in the Plan and all other arrangements with respect to which deferrals of compensation are treated as having been deferred under a single nonqualified deferred compensation plan under Code Section 409A and applicable guidance thereunder (i.e., this Plan and the NiSource Inc. Executive Deferred Compensation Plan), then the form of payment of both the Pre-2005 Benefit and Post-2004 Benefit shall be a single lump sum.

ARTICLE VIII

CLAIMS PROCEDURE

8.1 Claims Procedure. Claims for benefits under the Plan shall be made in writing to the Plan Administrator. The Plan Administrator shall establish rules and procedures to be followed by Participants and Beneficiaries in filing claims for benefits, and for furnishing and verifying proof necessary to establish the right to benefits in accordance with the Plan, consistent with the remainder of this Article.

8.2 Review of Claim. The Plan Administrator shall review all claims for benefits. Upon receipt by the Plan Administrator of such a claim, it shall determine all facts that are necessary to establish the right of the claimant to benefits under the provisions of the Plan and the amount thereof as herein provided within 90 days of receipt of such claim. If prior to the expiration of the initial 90 day period, the Plan Administrator determines additional time is needed to come to a determination on the claim, the Plan Administrator shall provide written notice to the Participant, Beneficiary or other claimant of the need for the extension, not to exceed a total of 180 days from the date the application was received. If the Plan Administrator fails to notify the claimant in writing of the denial of the claim within 90 days after the Plan Administrator receives it, the claim shall be deemed denied.

8.3 Notice of Denial of Claim. If the Plan Administrator wholly or partially denies a claim for benefits, the Plan Administrator shall, within a reasonable period of time, but no later than 90 days after receiving the claim (unless extended as noted above), notify the claimant in writing of the denial of the claim. Such notification shall be written in a manner reasonably expected to be understood by such claimant and shall in all respects comply with the requirements of ERISA, including but not limited to inclusion of the following:

8.4 Reconsideration of Denied Claim. Within 60 days of the receipt by the claimant of the written notice of denial of the claim, or within 60 days after the claim is deemed denied as set forth above, if applicable, the claimant or duly authorized representative may file a written request with the Benefits Committee that it conduct a full and fair review of the denial of the claimant’s claim for benefits. If the claimant or duly authorized representative fails to request such a reconsideration within such 60 day period, it shall be conclusively determined for all purposes of the Plan that the denial of such claim by the Benefits Committee is correct. In connection with the claimant’s appeal of the denial of his or her benefit, the claimant may review pertinent documents and may submit issues and comments in writing.

14

The Benefits Committee shall render a decision on the claim appeal promptly, but not later than 60 days after receiving the claimant’s request for review, unless, in the discretion of the Benefits Committee, special circumstances require an extension of time for processing, in which case the 60-day period may be extended to 120 days. The Benefits Committee shall notify the claimant in writing of any such extension. The notice of decision upon review shall be in writing and shall include specific reasons for the decision, written in a manner calculated to be understood by the claimant, as well as specific references to the pertinent Plan provisions upon which the decision is based. If the decision on review is not furnished within the time period set forth above, the claim shall be deemed denied on review.

If such determination is favorable to the claimant, it shall be binding and conclusive. If such determination is adverse to such claimant, it shall be binding and conclusive unless the claimant or his duly authorized representative notifies the Benefits Committee within 90 days after the mailing or delivery to the claimant by the Benefits Committee of its determination that claimant intends to institute legal proceedings challenging the determination of the Benefits Committee and actually institutes such legal proceedings within 180 days after such mailing or delivery.

The ONC Committee or the Board shall have the authority to amend the Plan.

Unless otherwise determined by the ONC Committee, the Benefits Committee shall have the authority to amend the Plan in all respects that are not exclusively reserved to the ONC Committee or the Board.

The respective committee may at any time amend the Plan by written instrument, notice of which is given to all Participants and to Beneficiaries.

The ONC Committee or the Company may terminate the Plan at any time provided that termination of the Plan shall not impair or alter such right to a benefit accrued under the Plan as of the effective date of such termination to or with respect to any Employee who has become a Participant in the Plan before the effective date of such termination or with respect to his or her Beneficiary.

Upon termination of the Plan, distribution of Plan benefits shall be made to Participants, surviving spouses and beneficiaries in the manner and at the time described in Article VI of the Plan.

Participants and Beneficiaries shall be unsecured general creditors, with no secured or preferential right to any assets of the Company, any other Employer, or any other party for payment of benefits under the Plan. Obligations of the Company and each other Employer under the Plan shall be an unfunded and unsecured promise to pay money in the future.

10.2 Income Tax Payout.

16

10.3 General Conditions. Except as otherwise expressly provided herein, all terms and conditions of the Basic Plan applicable to a Basic Plan benefit shall also be applicable to a benefit payable hereunder. Any Basic Plan benefit shall be paid solely in accordance with the terms and conditions of the Basic Plan and nothing in the Plan shall operate or be construed in any way to modify, amend or affect the terms and provisions of the Basic Plan. Defined terms used in the Plan that are not defined in this Article or elsewhere in the Plan but are defined in the Basic Plans shall have the meanings assigned to them in the Basic Plans.

10.4 No Guaranty of Benefits. Nothing contained in the Plan shall constitute a guaranty by the Company or any other Employer or any other entity or person that the assets of the Company or any other Employer shall be sufficient to pay any benefit hereunder.

10.5 No Enlargement of Employee Rights. No Participant or Beneficiary shall have any right to a benefit under the Plan except in accordance with the terms of the Plan. Establishment of the Plan shall not be construed to give any Participant or Beneficiary the right to be retained in the service of the Company or any other Employer.

10.6 Nonalienation of Benefits. No interest of any person or entity in, or right to receive a benefit under, the Plan shall be subject in any manner to sale, transfer, assignment, pledge, attachment, garnishment, or other alienation or encumbrance of any kind; nor may such interest or right to receive a benefit be taken, either voluntarily or involuntarily, for the satisfaction of the debts of, or other obligations or claims against, such person or entity, including claims for alimony, support, separate maintenance, and claims in bankruptcy proceedings.

17

Notwithstanding the preceding paragraph, the Supplemental Savings Account of any Participant shall be subject to and payable in the amount determined in accordance with any qualified domestic relations order, as that term is defined in Section 206(d)(3) of ERISA. The Plan Administrator shall provide for payment of such portion of a Supplemental Savings Account to an alternate payee (as defined in Section 206(d)(3) of ERISA) as soon as administratively possible following receipt of such order. Any federal, state or local income tax associated with such payment shall be the responsibility of the alternate payee.

10.7 Applicable Law. The Plan shall be construed and administered under the laws of the State of Indiana, except to the extent preempted by applicable federal law.

10.8 Incapacity of Recipient. If any person entitled to a benefit payment under the Plan is deemed by the Plan Administrator to be incapable of personally receiving and giving a valid receipt for such payment, then, unless and until claim therefor shall have been made by a duly appointed guardian or other legal representative of such person, the Plan Administrator may provide for such payment or any part thereof to be made to any other person or institution then contributing toward or providing for the care and maintenance of such person. Any such payment shall be a payment for the account of such person and a complete discharge of any liability of the Company, any other Employer, the Plan Administrator and the Plan therefor.

10.9 Unclaimed Benefit. Each Participant shall keep the Plan Administrator informed of his or her current address and the current address of his or her Beneficiaries. The Plan Administrator shall not be obligated to search for the whereabouts of any person. If the location of a Participant is not made known to the Plan Administrator within three years after the date on which payment of the Participant’s benefit may first be made, payment may be made as though the Participant had died at the end of the three-year period. If, within one additional year after such three-year period has elapsed or within three years after the actual death of a Participant, the Plan Administrator is unable to locate any Beneficiary of the Participant, then the Plan Administrator shall have no further obligation to pay any benefit hereunder to such Participant, Beneficiary, or any other person and such benefit shall be irrevocably forfeited.

10.10 Limitations on Liability. Notwithstanding any of the preceding provisions of the Plan, none of the Company, any other Employer, or any individual acting as an employee, or agent at the direction of the Company or any other Employer, or any member of the Benefits Committee, the ONC Committee or any delegate of such committees, shall be liable to any Participant, former Participant, Beneficiary, or any other person for any claim, loss, liability or expense incurred in connection with the Plan.
